Abstract: The invention comprises dyestuffs, free from groups imparting solubility in water, of formula <FORM:0821029/IV(c)/1> where B is a 3,31-dichlorodiphenyl residue bound to the azo links in 4- and 41-positions and R is a benzene residue containing the Aroyl-NH-group in o-, m- or advantageously in p-position to the -HN-CO-group.  They are made by conventional methods by coupling a tetrazotized 3,31-dichloro-4,41-diaminodiphenyl with a compound of formula Aroyl-NH-R-NH-COCH2-Aryl.  Coupling may be effected in substance, advantageously in a weakly acid medium in the presence of a wetting or dispersing agent, or on a substratum or, preferably, on the fibre. Stabilized tetrazo compounds, e.g. diazo-amino compounds, are preferably used when the dyestuff is formed on the fibre.  Preferred coupling components are benzoylacetic acid arylides and particularly acetoacetic acid arylides of formula <FORM:0821029/IV(c)/2> where R2 is a benzene residue and one of the X's is MeO or EtO and the other is halogen or, advantageously, MeO or EtO.
